Benefits of technology

The patent text is describing the terms "ashiness" and "pastiness," which refer to the white/blue hue that can be observed on skin after applying a cosmetic product that provides high coverage. The technical effect of this patent is to provide a better understanding of the characteristics of these two terms and how they can be used to improve the quality of cosmetic products.

Problems solved by technology

The technical problem addressed in this patent is how to achieve a high level of coverage without compromising the natural appearance of the skin or causing unevenness or whiteness across the face or body. Additionally, it seeks to reduce the negative effects caused by reflected light, including ashiness and pastiness, which can result from wearing makeup containing certain ingredients like titanium dioxide.

[0102]A liquid foundation of the present invention is prepared as follows: in a suitable vessel, water, glycerine, disodium EDTA and benzyl alcohol are added and mixed using conventional technology until a clear water phase is achieved. When the water phase is clear, the methylparabens are added and mixed again until clear. The resultant phase is mixed with a Silverson SL2T or similar equipment on high speed (8,000 rpm, standard head). In a separate vessel, the dimethicone & dimethicone copolyol cross-polymer, cyclopentasiloxane, pigment dispersion, other oils, dispersant and the parabens are added and the mixture is milled using a Silverson SL2T on a high speed setting until a homogeneous mixture is created.

[0103]Following this step, the water phase and the silicone phase are combined and milled using the Silverson SL2T on a high speed setting until the water is fully incorporated and an emulsion is formed. The dimethicone crosspolymer & cyclopentasiloxane is then added and the mix...

[0104]A liquid foundation of the present invention is prepared as follows: in a suitable vessel, water, propylene glycol, methyl paraben, sodium chloride and poly vinyl pyrrolidone are added, heated and mixed using conventional technology until a clear water phase is achieved. The resultant phase is cooled to room temperature. In a separate vessel, cyclopentasiloxane, pigment dispersions, other oils, dispersant, propyl paraben, Iron containing titanium dioxide, transparent iron oxides and the waxes are added and the mixture is mixed whilst it is heated. Once the waxes are well dispersed, the mixture is milled using a Silverson SL2T on a high speed setting and allowed to cool to 55° C. when the powders, trihydroxystearin and linear silicones are added. Once both phases are at room temperature, the water phase and the silicone phase are combined and milled using the Silverson SL2T on a high speed setting until the water is fully incorporated and an emulsion is formed.

Abstract

Processes for reducing the appearance of ashiness or pastiness on skin by applying thereto a cosmetic composition comprising transparent iron oxide particles, iron-containing titanium dioxide particles, and a cosmetically acceptable carrier. These processes are useful to provide coverage of skin imperfections and/or skin tonal variations and/or skin discoloration surrounding the eyes on different types of skin, while, at the same time, retaining a natural skin appearance.
